The tool is for Polaris motor driven clutches. I used it on a Deere 825i clutch(2012 model) after making a clutch holder.I was unable to loosen the spider.It seems Deere has placed huge torque and or used thread lock compound on the spider. Heat did not work.I used mineral spirits to clean a clutch with only 150 hours since it was fine dirt preventing the clutch from opening all the way.I plan to clean the air tube intake filter on a regular basis to prevent fine dust from fouling the clutch.
